twenty; of the Surf not more than ten, and of the Red-throated Loons 

 a single pair. The Grebes were in small scattered companies, numbering 

 in all about twenty Horned and twelve or fifteen Holboell's, all in dingy 

 winter plumage. We shot a few of the HolbcEll's, and found them to 

 vary much in size, and in the length and color of the bill, but scarcely at 

 all in plumage. Both kinds of Grebes lingered on the lake for several 

 days, after the other refugees had gone. On one morning near the end 

 of the storm (Oct. 12), all the Ducks and Grebes and the two Divers were 

 together, — in our little mountain pond-hole barely more than a mile long.

RECENT LITERATURE. 



The International Catalogue of Scientific Literature. — The first 

 annual issue of the International Catalogue of Scientific Literature, com- 

 prising the literature of the year 1901, consists of a volume for each of 

 the seventeen branches of Science into which scientific literature is 

 divided for the purposes of the Catalogue. These branches are indicated 

 by the letters A to R, Zoology being branch ' N ' of the series. A copy 

 of Volume N^ having been officially sent to 'The Auk' for review, we 

 have endeavored to give it the careful consideration its great im.portance 

 demands. 



The ' International Catalogue of Scientific Literature ' is an outgrowth 

 of the well-known ' Catalogue of Scientific Papers ' published by the 

 Royal Society of London, which in twelve large quarto volumes covers 

 the period 180Q-1SS3. A Catalogue covering the period 1884-1900 is now 

 in preparation, to be issued under the same auspices. These volumes 

 give only the titles of papers, but a subject index to the first series, 

 " which will serve as a key to these volumes and also form an independ- 

 ent record, is in an advanced state of preparation." 



The possibility of preparing a complete index of current scientific liter- 

 ature, to include subject indexes as well as titles of papers, began to be 

 considered by the Royal Society in the year 1S93. As it was apparent 

 that the resources of the Society were inadequate for such an undertak-
